Abstract |
Operational control parameters of the activated sludge process during steady-state and transient flow conditions were evaluated and related to carbon, nitrogen, and phosphorus removals. During steady-state testing, chemical oxygen demand, net growth rate, aeration tank detention time, and final settling tank detention time were found to be the key operational control parameters. Changes in COD removal and suspended solids removal were proportional to a change in control parameter. Nitrogen removal was related to specific operational parameters and system nitrogen balances were computed. Phosphorus removal without external chemical addition was related to specific operational parameters. (Author) |
